Patent ES-275362-A1 (ES)
Title: Means for increasing the catch range of a phase detector in an afc circuit
IPC: H04N5/12
Filed: 1962-03-10
Abstract: A symmetrical transistor 4 acts as a phase detector between incoming sync, pulses 14 and a television receiver line flyback pulses 9, differentiated by capacitor 11 to produce a sawtooth reference wave 16, and producing across an output capacitor 15 an A.F.C. control voltage stabilizing the line oscillator 2. Further, the capacitor 15 is arranged to maintain the extreme, i.e. maximum positive or negative instantaneous values of the sawtooth 16 at instants when the sync. pulses 14 do not coincide in time with the flyback pulses 9 or sawtooth 16, so that this instantaneous A.F.C. voltage, indicating the sense of the frequency error, increases the system pull-in or catching range during conditions of substantial frequency error of the oscillator 2. To this end the transistor 4 is arranged only to receive sync. pulses 14 rendering it conductive when the pulses 14 and flyback pulses 26 (coincident with flyback pulses 9 but opposite in polarity) are coincident in timing on a coincidence detecting transistor 20. The latter is normally conductive to by-pass to earth the pulses 26 but is rendered non-conductive during the pulses 14 so that corresponding width negative pulses (samples of pulses 26) are only during coincidence of pulses 14, 26 passed to phase detector transistor 4.
Patent ES-280581-A1 (ES)
Title: Manufacture of peracetic acid
IPC: C07C409/26
Filed: 1962-09-06
Abstract: Peracetic acid is produced by reacting acetaldehyde with oxygen in the vapour phase in the presence of at least 17.5% by weight, based on the acetaldehyde, of a solvent for peracetic acid. The process may be continuous by reacting the acetaldehyde and oxygen together, passing the reaction product to a fractionating column to which a solvent is fed, recovering the solution of peracetic acid at the bottom and recycling unreacted acetaldehyde vapour from the top of the column mixed with at least 17.5% of the solvent to the initial reaction zone. The solvent is one which boils below 80 DEG C., e.g. acetone. The temperature at the top of the column is preferably at least 25 DEG C., e.g. 35 DEG to 45 DEG C. and is the temperature of the acetaldehyde/solvent mixture. Specifications 547,333 and 927,053 are referred to.
Patent ES-315188-A1 (ES)
Title: Fuel injection systems
IPC: G05D16/16
Filed: 1965-07-10
Abstract: In a continuous, low-pressure fuel injection system an engine-driven pressure pump, Fig. 2, supplies fuel to a housing 32 containing an engine-driven rotor 33 which contains a ball 38 movable in a radial guideway formed by toothed members 37. The fuel pressure in the housing 32 assumes a level which balances the centrifugal seating force acting on the ball and fuel flowing round the ball passes via the central chamber 35 and relief valve 41 back to the float chamber 6. Relief valve 41 may be omitted. A fuel metering valve 13 has a piston 88, Fig. 5, and compartment 98 exposed to the inlet manifold pressure respectively via port 106 and flow restrictor 109 and via port 108. Diaphragm 97 is flexed to increase the seating force on valve 94 thereby decreasing the leakage of ambient air into chamber 61 and increasing the vacuum therein. Piston 88 moves to compress spring 102 which exerts an unseating force on valve 94 and takes up a position dependent on the inlet manifold pressure thereby pivoting cam 78 to move cam follower 80 thus rotating valve 67, Fig. 7, to vary the metering orifice defined between V-slot 68 and aperture 71 in sleeve 69 which in turn controls the fuel flow from inlet 75 to outlet 77. A screw 83 meshes with a gear 82 on sleeve 69 to provide datum adjustment of slot 71.

Patent ES-336859-A1 (ES)
Title: Device for correcting the measurement of potentials detected by contact electrodes
IPC: H03F3/40
Filed: 1967-02-15
Abstract: In the measurement of the potential of a human organ, e.g. heart, brain, muscles &c., in which contact electrodes are placed on the skin, the potential drift due to the polarization of the electrodes is compensated for by subtracting from the measured potential a linearly increasing potential equal to the polarization potential. The potential across the electrodes 1, 2, Fig. 2, is fed to the input of a differential amplifier 3 whose second input 14 is provided by the attenuated output from an amplifier 5, connected in parallel with a capacitor 6, whose input is provided either by the output of amplifier 3, via switch 9, or the voltage on the slider of a potentiometer 12, via switch 11. For setting the zero of the amplifier 3, switch 9 is closed either manually or automatically capacitor 6 is charged to the level of the output from the amplifier 3, equal to the potential initially existing between the electrodes. When switch 9 is opened the capacitor discharges applying the voltage to the input of the amplifier 3 via attenuator 7 which is reset to give zero output. In use with switch 11 closed and switch 9 open, a linearly increasing voltage is applied to input 14, whose slope is arranged to be equal to that of the polarization potential by alteration of the slider of the potentiometer 12.

Title: Device for forming successive folds from a web of textile elements
IPC: D04H11/04
Filed: 1967-02-20
Abstract: A warp 4 of natural or synthetic textile yarns is corrugated, e.g. in the manufacture of a carpet, by successively pushing parts of the warp 4 between blades 18 on a cylinder 5 by folding rollers 20 each of which is moved, between adjacent blades 18, across the warp 4 from one longitudinal edge thereof to the other longitudinal edge. In the machine shown, the warp 4 is guided by rollers 6, 7 and a bar 8 and when formed with corrugations 2 is bonded to a backing 3 which carries an adhesive layer thereon. The cylinder 5 is mounted on a shaft 9 driven from a main shaft 11 by bevel gears 13, 14, a shaft 15, a wormscrew 16 and a toothed wheel 17. The blades 18 are parallel to the horizontal axis of the shaft 9 and the inner faces thereof are rough to assist in retaining the corrugations 2. The folding rollers 20 are each freely rotatable on a pivot 21 secured to a movable support 22 attached to the machine frame 31. The path of the rollers 20 includes an essentially horizontal portion which is slightly oblique to the axis of the shaft 9 and is followed by a rising portion and a returning descending portion. Each roller 20 is provided with a folding ring 33, Fig. 4, which moves at a given distance from the cylindrical face of the cylinder 5. Retaining rings 34, 35 of the same external diameter as the ring 33 are also provided on the roller 20 to control the bottom of the formed corrugations 2. The rings 33, 34, 35 have entirely circular peripheries but, in a modification to obtain corrugations of varying height across the width of the warp 4, are only circular on parts of their peripheries and comprise flat portions or arcuate segments on the remaining parts. In a modification, Fig. 5 (not shown), to form a cut pile carpet of even height, the ring 35 is replaced by a knife (36) having an outer diameter greater than that of the rings (33) (34). In a further modification, Fig. 6 (not shown), to obtain a textured carpet with upper and lower looped pile, in each group of three folds, one fold is higher than the remaining two folds. In another modification, Fig. 7 (not shown), to obtain a textured cut pile, a folding ring and a retaining ring of different heights and a knife to out the shallow folds only are provided.

Patent ES-443930-A1 (ES)
Title: Inter-related switching, activity compression and demand assignment
IPC: H04B7/15
Filed: 1975-12-29
Abstract: Digital exchange terminals are linked by earth satellite in a privately coordinatable time division switching and communication network system serving multiple voice telephone and data communication lines. Terminals operate in each satellite time division frame to pass information switchably between variously paired lines and groups of n buffer stores, and between up to m (less than n) stores of each group (addressed in predetermined time order as internal time division channels termed virtual channels) and associated time-ordered groups of up to m external (satellite) channels. The selective switching between internal and external channels is termed activity compression handling. The external channels are adaptively appropriated to the terminals by demand assignment. Demand information exchanged between terminals at all network nodes is processed through a predetermined and pretimed reassignment computation process executed at all terminals. The terminals then exchange information representing proposed (bid) reassignments of external channels. In the absence of conflict the bid assignments are instituted. The activity compresssion acts as an intrinsic limiting factor on demand when more than m virtual channels are occupied.
